Question

CAN SOMEONE PLEASE HELP OR EXPLAIN HOW TO DO IT ... 6. If ABC-ADEF and the scale factor

Answer 1

Answer:

5

Step-by-step explanation:

One is given that the scale factor to get from triangle (ABC) to triangle (DEF) is ($\frac{1}{2}$). This essentially means that one has to multiply the sides of (ABC) by ($\frac{1}{2}$) to get the corresponding side in the triangle (DEF).

As one can see, side (AB) corresponds to side (DE), therefore, multiply the length of (AB) by ($\frac{1}{2}$) to get the side of (DE).

AB * $\frac{1}{2}$ = DE

Substitute,

$10*\frac{1}{2}=DE$

Simplify,

$5=DE$

($ED$) is another way of naming segment ($DE$) this is explicitly clear from the diagram of the tirnagles.
